Replacement battery for ASUS ROG Zephyrus Duo 15

This 90 Wh lithium-ion pack replaces the original C41N1906-1 unit in GX550 and GX551 series laptops. It delivers 15.4 V and 5845 mAh across four cells for restored runtime. The long cable eases installation in the dual-screen chassis.

Thermals and power behaviour

The 15.4 V output matches the factory specification so the laptop's charging circuit operates normally. CE, FCC and RoHS certification confirms the protection circuitry limits over-current and over-voltage events. Low self-discharge keeps the pack ready after weeks of storage.

Build quality and daily fit

A black hard-shell casing fits the existing battery bay without modification. The extended flex cable routes around the secondary display hinge cleanly. Compatibility spans the full GX550, GX551, FA506, FX506 and FA706 model families listed by the manufacturer.

Questions about this item

How do I install the C41N1906-1 battery in my ASUS GX550, and what step is often missed?

Remove the bottom cover screws, disconnect the old battery cable first, then connect the new 15.4V 5845MAH pack before refitting the cover; the long cable on this unit must be routed clear of the fan and hinge brackets or it can be pinched.

What maintenance will the 4-cell lithium-ion pack need later?

No routine maintenance is required; keep the battery between 20 % and 80 % charge when stored, avoid deep discharges, and replace the pack once run-time drops below your needs.

What limit appears first under sustained load on this 90WHR battery?

The 15.4V 5845MAH cells will hit thermal and voltage sag limits before the 90WHR capacity is fully used, so heavy gaming sessions may throttle run-time earlier than light workloads.
